1. Yeah, they do sell merch. I think adult sized shirts run under 20 bucks. I bought a MCMG shirt years ago and I want to say it was only 15 bucks.

2. Any live TNA event is a good one. They're very interactive with their fans before and after the show, going as far as surrounding ringside after the show goes off and giving out autographs and taking pictures with fans. I know at one point Val used to come around with the titles to let people hold them and take pictures They even charge about 20 bucks I think for an in-ring picture with one of the big name wrestlers, but that bit might just be for house shows.
